sPLloE-BAR.

i l Y Be it known vthat we, RALrH V. SAG-E and ,Y GEORGE E. THAcxRAn citizens of the United States, residing in` the lborough of Westmont, inthe county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in S lice-Bars; andwe do `herebydefclare the `fo lowing to be a full,

members have `also generally been madev of length equal to or shorter than the space beL I tween the ties ,which requires that the largest part of thelower portion of the stock-bar be f cut away,with consequent loss as scrap, and

are distorted by cooling The reinforcing for all of these reasons such `splice-bars have consequently been expensive in manufacture.`

Inthe manufacture of our splice-bar allof the objectionablefeatures above referredto rare avoided, as our stock-bar isl made sym-A metri cal in Vcross-section with respect toits central longitudinal plane, making `a yshape lwhichis cheaplyfand easily` rolled, without rvenient and proper section for shearing' the straightening. Our stock-bar is also of con-A splice-bars alternately and reversely from n opposite sides thereof, thereby effecting `a saving in material. 1 u

.An embodiment of our invention is shown in the accompanying sheet ofdrawings, in i which like characters of reference designate `like parts.` v u l Referring to the drawings, Figure l isa side elevation of a rail-joinshowing the preferred form of our improved splice-bar in position. Fig. 2 is a view corres onding to u Fig. `l, showing a modified form o the same; l Fig.` Sis a transverse sectional elevation taken o n planes indicated by the broken lineIH Ill. of Fig. 1 showingthe cross-section of the spliceebar and the "manner of assembling a -pair of them at a rail-joint. Fig. 4 is a plan viewv of a stock-bar, showing the manner of cutting the preferred form of splice-bar therefrom. Fig. 5 is a view corresponding to'Fi 4, showing the mannerof cutting the mod' ed form. i In the drawings, 1A designates the endsof adjacent rails, which are united `and'supported in the` usual manner by thegirder splicebars 2 and the track-.bolts 3. Each Vof these` splice-bars comprises a splice member tandY a reinforcing member 5, which latter extends below the former,` is. located opposite/the joint ofthe rails and preferably equidistant from the ends.` The renforcing'members are designed to-.be secured together, as byl ,bolts 6, the separator-blocks 7 serving"` to roo Y space them a'proper distance` apart, whereby the usual track-bolts,l are assisted in holding.v

the splice members firmly in contact with both the head and the flange of the rail. By these'v means a strong noisele'ss splice is provided which still has the required elasticity. If greater elasticity is desired, the bolts 6 and their separator-blocks may be omitted without impairing the strength of the joint or departing fromour invention.l The reinforcing members 5 also serve to prevent the creeping of the rails by placing one or the other of their edges so that they abut against the tie, or, if so desired, they may' b'e made of such a length as will fill the 'space between the adjacent ties; it is the intention to etil'iz'e the reinforcing member for this parpose,- the edges thereof are' preferably made" at right angles to the splice member, as Shown' at 81.' @thm-Wise the' prefer-able Construction is as shown at 9, where the edges forni an obtuse angle with the splice member, making a wider4 base and reducing the stresses inl the rentrant' angles, whereby a stronger structure is producedwithsubstantially'the same amount of material. The reentr'ant angles are also formed with round corners to strengthen the' structure.'

we make the reinforcing member of substanmember, thus rendering the stock-bar sym;

Y' metrical in cross-section, whereby-it' is more cheaply and easily rolled and remains straightv upon cooling.

from the stock-bar and the consequent econ- 'omy of work and material resulting fromV the shape and arrangement thereof are shown in Figs. 4 and' 5, the former applying'to the form shown in Fig. l and the latter to the forni shown in Fig. 2. It may be stated that the ends ofthe form shown in Fig. 2 may be left oblique', as shown in Fig. 5', or theymay be cut square, as indicated by dotted lines. In order to provide space for the blades of the shears, the stock-bar is' made with a centrally-located plane web 10. This web may be wide enough in proportion to' the thickness of the blade of the shear to permit the cut t'obe made in the middle thereof; but' preferably ity is of a width (shown in the drawings) which requires a primary cut to be made on one side thereof and two secondary cuts on the opposite side, thereby cutting away asmall part indicated by the shaded portions of Figs'. 4 and 5,. The -flat surface or' central web 10, extending vertically below the rail-flange, is' also of service in rolling the section, as it can thus be produced by the tongues on the ordinary rolls without undue wear, as these tongues can be made of aA reasonable width, thus reducing the intensity of the friction and pressure on the same.

From the above description the advantages of our. invention will readily be seen. A splice-bar is formed which is exceptionally nation wit y splice members and shorterrelnforclng memstrong in pro ortion to its weight and yet has the desired e as'ticity, due to the proper distributionof the metal. It is also very cheap to manufacture, since it is cut directly from a stock-bar without further operations upon it except the punching of the holes for the bolts and with little or no waste material. The'stock-bar itself is more easily produced in consequence of its symmetrical cross-section, making itv easier to roll and requiring no straightening after cooling.

As heretofore stated, we may omit the bolts 6 and the' separater-blocks 7 case a more yielding joint or' one of greater elasticity is desired, and we may also make these separater-blocks 7 of 'yielding material-such as wood, fiber, metallicy springs, or other construction-#such as to' permit the splice-bar to be adjusted or drawn together by the bolts to` insure a good fit and "osition desired.

p A number o'f mod' `cations of the' invention will readily suggest themselves to one skilled l in this art. this application to the precise forms shown l therein, but to have it construed as broadly as the invention' merits.

In order to reduce the cost of manufacture, I'

the sides of the depending portion being substantiailly at right angles to the longitudinal axis of the bar, therebyy forming an anti-railereeping device, and Ineens for securing said bars to the rails.
